I Applicatioirfiled February 14,1906. Serial No. 301,048-

To all whom it may concern:

Be it known that I, GUsTAv AUGUsT WEIHE, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have in vented certain new and useful Improvements in Non-Refillabl-Bottle Stoppers, of which the following is a specification.

My invention relates to non-refillable-bottle stoppers, and has for its object the provision of a device of this character which will be simple in construction, may be cheaply manufactured, and will permit liquid to flow from a bottle, but will prevent the bottle from being refilled after it has once been emptied.

A further object of the invention is the provision of means for permitting liquid to flow from a bottle, but will prevent said bot-- tle from being refilled after it has once been emptied, said means being contained in a casing which may be manufactured apart from the bottle proper and which may be readily applied to bottles already in use.

Further objects and advantages of the invention will be set forth in the detailed deresponding scription which now follows.

In the drawings, Figure 1 is a vertical sectional view of the neck of a non-refillable bottle constructed in accordance with my invention. Fig. 2 is a similar view showing the bottle tilted at right anglesto the position which it occupies in Fig. 1. Fig. 3 is a detail sectional view of a stopper ca'sing hereinafter described. Fig.4 is a top plan view of one of the disks comprising the non-refillable-bottle stopper. Fig. 5 is a bottom plan view of said disk. Fig. 6 is a detail perspective view of a valve hereinafter described,

and Fig. 7 is a plan view of a valvo-retaining cup hereinafter described.

Like numerals of reference designate corparts in all the figures of the drawings.

Referring to the drawings, the numeral 5 designates the neck portion of an ordinary bottle. Secured within saidneck portion of the bottle is a stopper-casing 6, having an outletopening 7. Cemented within the stopper-casing 6 1s a disk 8, provided with inclined ports 9. A valve-retaining cup 10, the bottom of which is partially closed by a web 11, has an opening 12 formed through said web 11, said web normally forming a seat for the valve 13. The valve 13 is provided with upstanding lugs 14 at each corner thereof.

The operation of the device is as follows: After the bottle has been filled the stoppercasing 6' and the parts carried therein are cemented within the neck of the bottle. When the bottle is inverted, the valve 13 falls against the face of disk 8, the lugs 14 preventing the face of the valve 13 from contacting with the face of said disk to close the ports 9. The liquid will then flow from opening 12, ports 9, the upper portion of casing 6, and pass from the outlet-opening 7 ,it being understood that said outletopen ing is normally closed by a stopper 15. It will be readily understood that when the bottle is in the position shown in Figs. 1 and 2 the opening 12 is closed to prevent the passage of liquid from the opening 7 and ports 9 to the interior of the bottle.

From the foregoing description it will be seen that a bottle-stopper is herein provided which accomplishes the objects of the 1nvention, which may be cheaply manufactured, and which may be inserted in the neck of bottles already in use without changing the structure of the said bottles.

While the elements herein shown and described are well adapted to serve the purpose for which they are intended, it is to be understood that my invention is not limited to the precise construction set forth, but includes within its purview such changes as may be made within the scope of the appended claims.

Having described my invention, what I claim is 1. In a device of the character described, the combination with an open-ended casing, of a disk spanning said casing between the ends thereof, said disk having ports formed therethrough, a cup located in said casing beneath said disk, said cup being formed in its bottom with a central port and a valve Within said. cup, adapted to close said lastnamed port said valve being formed with upstanding lugs adapted to engage the underneath face of said disk and maintain said valve in spaced relation thereto, in its open position.

2. In a device of the character described, a casing formed with an open bottom, and a cone-shape top, said top being formed with a central opening of constricted diameter for said disk and maintain said valve in spaced the reception of a stopple, a disk spanning relation thereto. [0 said casing centrally thereof, a cup spanning In testimony whereof I afliX my signature said casing adjacent to the bottom thereof in presence of two witnesses.
